Abstract (en)
[origin: EP1791199A1] A negative-electrode material for a lithium secondary battery is provided that can be produced through a simple procedure and can yield a lithium secondary battery having a high electrode-mechanical strength, being excellent in immersibility, involving a small initial irreversible capacity, being excellent in charge-discharge characteristic under high current densities, and having a high cycle retention ratio, i.e. having an excellent balance of various battery characteristics. The material includes particles (A), which are selected from the group consisting of carbon-material particles, metal particles, and metal-oxide particles, and two or more different polymeric materials each attached to different sites of the particles.
